Port Performance View
SNMP NB30 Local Port Performance View
This button accesses a rate graph displaying the number of giant packets over
a given time frame. Fields to each side of the button indicate the amount of
giant packets that could not be transmitted by the port as both a total since
the bridge was initialized, and the total since the last poll. A giant packet
exceeds 1518 bytes not including preamble.
This button accesses a rate graph displaying the number of port collisions over
a given time frame. Fields to each side of the button indicate the total amount
of collisions detected by the port as both a total since the bridge was
initialized, and the total since the last poll.
Xmits Aborted
Indicates the number of attempted transmissions that have been aborted due
to excessive collisions as both a total since the bridge was initialized, and the
total since the last poll. Before SPECTRUM aborts transmission, over sixteen
attempts are made to send the packet.
OOW Collisions
Indicates the amount of collisions out of the standard window (51.2µs) due to a
network problem as both a total since the bridge was initialized, and the total
since the last poll.
CRC Errors
Indicates the amount of packets received by the port with bad Cyclical
Redundancy Checks (CRC) as both a total since the bridge was initialized, and
the total since the last poll.
Alignment Errors
Indicates the amount of misaligned packets detected by the port as both a
total since the bridge was initialized, and the total since the last poll.
